FAS is an abnormal condition of the hip joint. It is the knob and socket that make up the hip joint rubbing or hitting each other, and as a result, damage occurs in the hip joint.
Anatomy
The hip is a joint consisting of a knob and socket. The socket is formed by the large pelvic bone, while the knob is formed by the thigh bone called the femur. Cartilage tissue, which has a slippery structure, covers the socket and the knob and creates low friction surfaces.
In the inner part of the socket, there is a fibrocartilage half-moon-like structure called the labrum, on which the knob rests and acts as a shock absorber.

Definition
FAS occurs as a result of the development of bone protrusions on the edges of the knob or socket. These bone growths cause the hip joint to hit each other instead of moving freely. Over time, wear and tear in the articular cartilage and tears in the labrum occur, resulting in osteoarthritis called calcification.
There are three types of FAS: Pincer, Wedge and Combined types;
- Pinch Type; This type of jamming is caused by the socket. Excessive bone forms at the edge of the socket and crushes the labrum under it, creating compression.
- Wedge Type; This type of compression is caused by excessive growth on the edge of the knob, resulting in deterioration in the roundness of the knob.
- Combined Type; It is the situation where the wedge and pincer types are present at the same time.
Causes
During the growth period, the hip joint It is caused by abnormal growth of the bones forming the bone, and its cause is not clearly known. As a result, these excess bones in the hip cause damage to the joint, causing pain.
Clinical Findings
In these people, the pain is usually on the outer side of the hip, but sometimes it can also be in the groin area. The pain manifests itself in a stabbing or blunt manner when squatting or opening the leg to the side. In the early stages, it may start as a vague pain.
Physician Examination
After discussing your complaint, medical history and general health problems, your doctor will want to examine your hip.
Jam Test; This test is a special test that manipulates the hip joint and checks whether there is any compression in the joint.
G� �imaging
X-ray, computed tomography and MRI may be requested to help and support the diagnosis.
- X-ray; It is a good imaging in terms of calcification and excess bone.
- Computed Tomography; It gives more detailed information than an x-ray and shows abnormal bones in the hip.
- MRI; It provides very good imaging of soft tissues. It is very useful in terms of showing the damage to the labrum and joint cartilages in detail.
Treatment
Non-Surgical Treatments
Activity arrangement; It is recommended that you avoid movements that cause pain.
- Medication; Non-steroidal painkillers should be used.
- Physical Therapy; Exercises to strengthen the muscles that increase and support hip joint movements are recommended.
Surgical Treatment
Your pain will not go away with non-surgical treatments. and if there is joint damage, your doctor may recommend surgery.
Most FAS problems benefit from surgical treatment. For this, arthroscopic repairs are planned using small tools, small incisions and a camera.
In arthroscopic repair, bone growths and labrum around the hip joint are cleaned and repaired. In some cases, open surgery may be required.
